The structural principle of Ruibei e-commerce hand chain hoist investment hotline 96559

Hand chain hoist. ． As an upgraded version of the fixed pulley, it completely inherits the advantages of the fixed pulley. At the same time, it adopts the combination of reverse backstop brake reducer and chain pulley block, and has a symmetrically arranged two-stage spur gear rotation structure, which is simple, durable and efficient.
When the hand chain hoist lifts a heavy object upward, pull the manual chain and hand chain wheel clockwise to rotate, pressing the friction plate ratchet and brake seat into one body to rotate together, and the long tooth axis will rotate the plate gear, short tooth axis and Spline hole gear. In this way, the lifting sprocket installed on the spline hole gear drives the lifting chain, thereby lifting the heavy object smoothly. When descending, pull the hand chain counterclockwise, the brake seat is separated from the brake pad, the ratchet is stationary under the action of the pawl, and the five-tooth long axis drives the lifting sprocket to run in the opposite direction, thereby smoothly lowering the heavy object. Hand chain hoists generally use ratchet friction plate one-way brakes, which can brake themselves under load. The pawl engages with the ratchet under the action of the spring.
Hand chain hoist makes the brake:. ． .safe job. It has the characteristics of safety, reliability, easy maintenance, high mechanical efficiency, small bracelet pulling force, light weight and easy to carry, beautiful appearance, small size, and durability. It is suitable for use in factories, mines, construction sites, docks, shipyards, warehouses, etc. It shows its superiority when installing machines and lifting goods, especially for open-air and non-power supply operations.
The main parts of the hand chain hoist are made of alloy steel, and the chain is made of high-strength lifting chain:/. ． .The material is generally medium-frequency quenching heat treatment, low wear and anti-corrosion chain high-strength hooks. The material is generally alloy steel. The forged hook design ensures slow lifting to prevent overloading and complies with European safety standards.
